Always will i upvote airships. I love the solar power potential! And dynamic aerodynamics. And come on, safe hydrogen harvested from the ocean, why not?

I wonder if it isn't possible to add a de-humidifier so it can remove water from air, elctrolyse it to and use to hydrogen to re-fill itself. Eternal balloons!

  With the huge power density of solar panels on its massive upper surface, why not?

    Just adding a huge amount of solar panels has other problems like massive thermal problems that would result in an expation of the helium inside. Source: I live in Friedrichsafen, the brithplace of the Zeppelin. Artur Brauchle Head of Electrics and Avionics at Zeppelin once told me this.

      So use the heat to turn water to steam. Steam-powered airships sound much cooler anyway.

      Yeah, problems that definitely need to be solved! Also, I almost went on a zeppelin this year, I didn’t know it was possible to still book them in your town!

      Sure, but did you have a credible source? Seriously, those must have been some unforgettable conversations. I'm a little envious.

This was initially a good laugh: https://news.ycombinator.com/item?id=24739220 https://news.ycombinator.com/item?id=24739220 . Since one cannot reply to that post anymore, turning the monitor off is not a feature of a text editor; although font color is a feature the length or presence of entered text is visible by the cursor position & neither options disable editing (append only?). Using a command similar to this on a POSIX terminal is an option to hide the input & seem to disable backspace & delete: echo "Thoughts?"; read -d $'\04' -s x; echo "$x"

  The actual request is a little more subtle: I think just a letter or two... Anything more and I'd want to edit. Anything less and I'd worry about whether it was working. But, I will try it with my screen off
